I live in the Dallas Texas area. I have an inground 'normal' gunite/plaster pool. The pool is approximately 17000 gallons and I use a DE filter.
I have a question about the big o-ring on the DE filter. The filter is a Stainless Steel Pacfab Nautilus 60 Sq Ft filter. The filter has been at my house longer than I have - I think it's about 30 years old (maybe 32). I can't really see the part number anymore.
Anyway - I needed to replace the o-ring. The one that is on there kind of has a trapezoid shape (if looking at a cross section of the band). The clamp band that goes around it has the same basic shape. I bought a replacement o-ring from a local chain pool supply store. The one they gave me is a normal o-ring. The person told me that the ring would take the 'trapezoidal shape' from the belly band. I wasn't sure if that's true but I tried. As much as I tried there was no way I was going to get that clamp ring tightened around that filter. I don't know how hard I would have had to force it to make that o-ring squeeze into the shape of that clamp band.
Does that sound normal? Did they make o-rings that had a 'not round' shape?
Does this even make any sense?
Thanks in advance
Jeff
